“This year I felt pressure, like we’re the underdog with something to prove,” said UO junior Laura Roesler, who repeated as conference champion in the 800. “If they’re going to keep ranking us lower and lower, we’re going just going to keep fighting harder and harder.”

Francis, Gardner, Prandini and Chizoba Okodogbe set the tone by winning the 4x00 in 43.81, nearly a second ahead of second-place USC.

Becca Friday, Anne Kesselring and Jordan Hasay finished 2-3-5 in the 1,500. Francis and Okodogbe went 1-2 in the 400, Francis winning in 51.57 and Okodogbe shredding the formchart by coming across second in 52.22, a personal record.

And so it went. Prandini won the 100, running 11.46 into a headwind. Roesler led Kesselring and Annie Leblanc to a 1-3-5 finish in a tactical 800.

In order, the meet record of 22.71 had been held by three-time Olympian Gail Devers since 1987, the stadium record of 22.86 had been set in 2005 by Monique Henderson, and Amber Purvis had owned the school record of 22.74 since 2010.

“I had some bitterness left over for the ‘2,’” Gardner said. “I basically got out there and ran my heart out.”

The 100 always has been a Gardner specialty. She has the NCAA’s best time this year in the event. Sunday she had to recalibrate for the 200.

“The 100 is my baby and the 200 is like my bad little son that never wants to sit down,” Gardner said. “I had to tend to him a little bit today, make sure he was good and fed. I’m happy with it.”

So was UO coach Robert Johnson, who watched Gardner, Francis and Prandini slam the door on Arizona. There were personal records all around. Francis crossed in 22.77 and Prandini in 23.15.

“That sweep was pretty special,” Johnson said. “For all three of those girls, after the workload they had today, to come out and run lifetime bests, that’s huge. That was the part of the meet where we figured we could really make a statement.”

The UO men were making statements for two days, loading up with a bushel of depth points to swamp the rest of the conference.

The day started well, with Greg Skipper and Miles Walk going 2-7 in the hammer. Both busted out personal records, Skipper throwing 222 feet 6 inches and Walk 196-11.

The UO men’s most impressive individual performance came in the 800, where Elijah Greer broke loose from a slow, tactical first 400 at the bell to win from in front in 1:49.48. He pulled teammates Boru Guyota and Chad Noelle to finishes of fourth and sixth respectively.

“It was the right time,” Greer said of his big move. “There is an advantage to being the first mover. When you can get a surge, get your move in, everyone is reacting to you. So if you can have five meters on someone, that means in his last 300 meters he has to run an extra five meters.”

The lead was 10 meters or more on the back straight as Greer put the field far behind him.

It was the UO men’s only individual victory on Sunday _ Dakotah Keys won the decathlon last week and Sam Crouser took the javelin on Saturday _ but there were Ducks contributing everywhere.

Johnathan Cabral was second in both the 110 and 400 hurdles. His time in the 400s of 50.50 was a personal record by nearly two seconds.

Mike Berry battled with USC’s Bryshon Nellum in an epic 400, Nellum pulling ahead on the home straight to win in 44.76. Berry was second in 45.14. Berry came back later to anchor Oregon’s 4x400 to victory in 3:05.63 as the Ducks closed the meet emphatically.

“We’re not Track Town USA for no reason,” Berry said. “We try to bring that everywhere we go. We take the Pac-12s as a big meet. We want to win every time.”

Berry never was faster than while making a getaway after dumping two cups of water on Johnson while the UO coach was being interviewed on camera after the meet.
